An investigation led by the Center for Ecological Research and Forestry Applications (Creaf) warns that the horseshoe snake (Hemorrhois hippocrepis), an invasive snake that already occupies 90% of Ibiza and can swim to the islets, "threatens" to extinguish the Pitiusa lizard (Podarcis pityusensis).

A study led by the Centre for Ecological Research and Forestry Applications (Creaf) warns that the horseshoe whip snake (Hemorrhois hippocrepis), an invasive snake that already occupies 90% of Ibiza and can swim to islets, "threatens" to extinguish the Balearic lizard (Podarcis pityusensis).

The GOB has warned that the recent "invasion" of snakes arriving from the mainland in Ibiza and Formentera is putting the Pitiusas lizard, a species endemic to the Balearic Islands, at extreme risk of extinction. Furthermore, they denounced that the efforts of the authorities to control the spread of these snakes, especially the horseshoe snake, are "insufficient" and the lizard's future "looks very bleak."
